API service with phone number authentication and a simple referral system.

Authentication in the service is based on the phone number format "+79608543017".

To start, obtain a 4-digit code by sending a POST request with the phone number to the POST /api/v1/auth/send_code/ endpoint.

Once the code is received, submit it along with the phone number to the POST /api/v1/auth/jwt/get_by_phone/ endpoint. Optionally, you can include an existing referral code from another user along with the phone number and 4-digit code.

If a user with the specified phone number does not exist, they are added to the database. After addition, the user is assigned a unique referral invite code.

Upon successful authentication, the response includes JWT access/refresh tokens (bearer auth). These tokens will be needed for accessing user endpoints and profile editing. Standard endpoints for token verification and refresh are also available: POST /api/v1/auth/jwt/verify/, POST /api/v1/auth/jwt/refresh/.

• GET /api/v1/users/: View the list of users. The invite_code field is the user's personal referral code, unique and assigned during user creation. The invited_by_code field is the referral code of another user who invited them to the service.

• GET /api/v1/users/{id}/: Retrieve information about a specific user.

• GET /api/v1/users/current_user/: Retrieve information about the current user.

On endpoints providing information about a specific/current user, there is an invited field with a list of user IDs and phone numbers who accepted the invitation from the viewed user.

• PATCH /api/v1/users/current_user/: Edit information about the current user. You can set the user's name, surname, email address, and the invite code through which they received the service invitation.
